IMPROVEMENT lN 'CULTlVATORS.

Specification forming part of Letters Patent No. 177,258, dated May 9, 1876; application filed February 2, 1876.

To all whom it may concern:

Be it known that I, WILLIAM LOUDEN, of Fairtield, county of Jefferson and State. of Iowa, have invented certain new and useful Improvements in Cultivators, of which the following is a full, clear, and exact description, and such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the annexed drawing, making a part of this specification, and in which- Figure 1 is an elevation of a cultivator-axle embodying my invention. Fig. 2 is a longitudinal sectional view, and Fig. 3 a transverse sectional viewon the line 00 m in Fig. 1.

The nature of my invention relates to improvements in the construction of axles for what is known generally as straddle-row cultivators; and the invention consists in making the arch, or central and main part, of the The walls of the pipe A being light, the heated metal of B will partly fuse it, and produce a secure union of the parts, which may, however, be strengthened by roughening the surface of the pipe A where the metal B incloses it. 0 Care the journals, to which the cultivator-plows are connected.

Heretot'ore these arched cultivatoraxles have been made of cast-iron, solid wroughtiron, and wood. The cast-iron is found liable to breakage, the solid wrought-iron too heavy, if made stifl' enough, and the wood expensive, When the arch is made of tubular iron the axle may be light, and still rigid, and the thinness of the metal, from bein g easily heated, facilitates welding the other parts thereto.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is'

The axle or beam-yoke of a straddle-row cultivator, constructed as described, with its arched central portion A made of tubular iron, and the side portions B B attached rigidly or cast thereon, in manner substantially as and for the purpose specified.

. WILLIAM LOUDEN.
